It’s fun and it’s free...

It’s fun and it’s free. Apart from a function to record/save your compositions [which is not included] what else do you need ?
I like to ‘compose’: airport/airline IATA/ICAO codes*, abbreviations, short words, numbers, symbols, etc., and listen to them.

* I work at London Heathrow Airport [LHR/EGLL] so that is an advantage!
